Posey, same Barbara, Calif. Application September 26, 1938, Serial No 231,' 715 A 3 Claims." (01. 210 -515) This invention relates generally to containers,

and more particularly to devices by whichliquid ,otone'specific gravity can be separated, from.

lliquidof a different specific gravity in a container,

and then removed from the container, such as, ,for example, the separation and removal o'fcream.

rom milk. c

,An, object of thev invention is; to provide a separator which is structurally characterized; in a novel and ingenious manner enabling it tobe as" an r ordinary milk bottle, for example, to separate cream at the top of' theb'ottlefrorn' the remainder of its contents,' and permit the separated cream to be conveniently poured from the bottle. I

separator of the above described character embodying a closure member which isinsertable as into the neckof the milk battle in a deformed condition and in a position causing but'negligible disturbance of the bodyoi cream at the top of the bottle, and is readily manipulated within the bottle to occupy'a partition-forming position at a as predetermined location of larger internal area of the bottle than at the smallest part of the neck,

so as to enable that portion of the bottles contents between the member and mouth of the bottle to be readily poured therefrom,

v A further object of the invention is to provide a separating device which is of simple and inexpensive construction and which can be easily sterilized.

With these-and other objects in view, the invention resides in the combinations and arrangements of elements as set forth in the following specification, and particularly pointed out in the appended claims.

In the accompanying drawing.

Figure 1 is a view of the invention in side elevation and illustrating the initial position thereof in inserting the separator or closure member into, a container such as an ordinary milk bottlegof illustrated;

the line 2-2 of'Figure 1; Figure 3 is a view similar to Figure 1 and illustrating the second position of the separator preparatory to sealing off the upper portion of the container from the remainder thereof;

Figure4 is a view also similar to Figure .1 and illustrating the final position of the separatorin separating the cream from the milk for pouring 55 from the bottle;

body of stainless spring steel-oi such gage as to utilized with a standard form-of container, such ther object offthe invention is to provide a of the links to form pivotal connections and has invention, which is as follows:

which the neck and a portion of the body is Figure 2 is a transverse sectional view taken on Figure 5 is a perspective view of the invention. Referring specifically to-the drawing, the invention-comprisesa separator or closure member'it which is preferably in-the' form of a disk enable it to be readily deformed laterally by be-- ing manually flexed to a bowed position'for insertion through the neck Ll of a milk bottle l2, the diameter of the member. being in excess .of the internal diameter of the neck at the mouthof the bottle and being such as to tightly span the bottle transversely, at a locationoi larger internal diameter thereof, such as at approximately the cream level :c in the bottle.

Th'e'member l5! s adapted to be manipulated 'by'meanfs of a lever handle I3 oper'atively connected to the member by means of a pair of links Hi pivotally connected at one end at it and it to the lever, with the spacing of the pivots being less than the internal diameter of the smallest part of the neck l I, which in the case of an ordinarymilk bottle is at the mouth thereof.

At their other end, the links are privotally connected in similarly spaced relationship to the member ill at diametrically opposite sides of the center thereof, by means of sleeves ll formed on 2 a metal straps I8 welded or otherwise secured to the member. It has been found in practice that piano wire provides an excellent material for the links it and It, as it is readily worked at the ends the ends of the links to form the pivotal cannections and has the requisite strength for their intended functioning in the operation of the member.

In the position of the closure member shown in Figure l, the handle and links are in substantially alined relationship, and the member is inserted edgewise through the bottle neck, so'as to cause but negligible, if any disturbance of the 7 contents of the bottle.

When the closuremember is thus inserted, the handle is swungto a position wherein it rests upon the lip of the bottle mouth 'toprovide a fulcrum point f, (Figure 4) it being clear that upon this lever movement of the handle a corresponding movement is imparted to the member I through the links [4 so that the member is now disposed transversely in the bottle and is loose therein as shown in Figure 3.

' Now, upon swinging the handle downwardly about the fulcrum 3 so as to cause an upward pull upon the links Hi, the closure member ID will be drawn into tight and substantially sealing contact of its peripheral edge with the internal surface of the bottle, it being understood that the closure member readily flexes laterally around its periphery sufliciently to compensate for slight inaccuracies in the bottle wall from a true circular form, so as to provide the necessary seal.

The handle is maintained in this position so as to hold the member in its partition-forming position as the bottleis tilted to pour off that portion of the bottles contents between the member and the mouth of the bottle.

After restoring the bottle to an upright position, the handle i3 is reversely swung to dispose the closure member in the position shown in broken lines in Figure 1, following which a pull is exerted upon the handle to draw the member from the bottle, it being clear that the member isdeformed to its bowed position by its camming engagement with the internal wall of the bottle neck as the withdrawing operation proceeds until the member is finally clear of the bottle and is free to spring back toits normal position. As the entire device is of indestructible material, it can be readily sterilized, which is absolutely essential in the case of physiological liquids, such as milk. 1

What is claimed is:

1. A separator of the class described comprising a flexible disk body insertable in a flexed condition edgewise through the neck of a container; a handle; and links pivotally connected at their ends to the handle andto said body respectively for insertion of the latter into the container as aforestated, the lengths of the links being such that manipulation of the body within the container by a fulcruming movement of the bandle on the container at one side of the links, can be efiected, to draw the body into a partition forming position at a location spaced from the outlet of the neck.

2 A separator of the class described comprising a flexible disk body insertable in a flexed condition edgewise through the neck of a container; a handle"; and a pair of links of substantially equal lengths pivotally connected at spaced points to the handle and to the body in a substantially parallelogrammic arrangement for co-action in enablin g the body to be inserted into the container as aforestated,- the lengths of the links being such that the handle can be manipulated by a fulcruming movement thereof upon the mouth of the container, to a partition forming position wherein the body contacts the internal wall of the container at a location spaced from the outlet of the neck.

3. A separator of the class described comprising' a flexible disk body; a handle; and links pivotally connectedat spaced points to the handle, and pivotally connected to the disk at opposite sides of the center thereof.
